Using Backup Options
Chapter 5 245
Encode
Open Systems and public networking make data security in large
enterprises essential. Data Protector lets you encode file and disk image
data so that it becomes unreadable. Data is encoded before it is
transferred over the network and written to the media. Data Protector
uses a fixed, built-in algorithm for this purpose.
The default value is OFF.
Expand Sparse Files (Novell Netware Specific)
By default, Data Protector backs up Novell NetWare sparse files in their
compressed format. Though this approach speeds up the backup process,
it makes it impossible to restore the Novell NetWare sparse files to any
non-NetWare platform. When this option is selected, Novell NetWare
sparse files are expanded before being backed up. Files backed up in this
form can be restored to non-NetWare platforms.
Lock Files During Backup
If set, files are locked while being backed up, preventing them from being
modified during the backup. Mandatory locking is used.
The default value is OFF.
With the option set for the NetWare Storage Management Service (SMS)
integration, the Disk Agent attempts to open files in the Deny Write
mode. If this attempt fails, the file is locked. If the file cannot be locked,
then it will not be backed up.
Logging
The default logging level is Log All. It can be changed to No Log, Log
Directories, or Log Files.
For more information on each logging level, see “Logging: Changing
Details About Data Stored in the Database” on page 231.
Number of Retries (Novell NetWare Specific)
The number that you enter in the Number of Retries text box is the
number of Data Protector’s attempts to back up a file. If a backup cannot
be made within this number of retries, Data Protector issues an error
message. If you use applications that open and release files, you can use
this option to increase the probability that the files are backed up.
The default value is 1.
